How to configure Walmart Marketplace API credentials

This guide explains how to set up Walmart Marketplace API credentials for Apideck's E-commerce API integration.

Prerequisites

• Access to Walmart's Channel Partner Portal
• Solution provider credentials from Walmart
• Apideck account with app ID and API key

Getting started

For production use, follow the standard OAuth2 flow instead of importing tokens:

Create a production app in Walmart

1. Log into the Channel Partner Portal with your solution provider credentials
2. Create a new application for production use
3. Copy your Client ID and Client Secret

Configure the production connector in Apideck

1. Log into Apideck Platform
2. Go to Configuration > E-commerce API > Walmart
3. Set the Client ID and Client Secret from your production app
4. Set the Server to "Production"
5. Save your settings

Connect via OAuth2 flow

Users can now create connections through the standard OAuth2 flow:

1. Navigate to Consumers
2. Create a new consumer
3. Add Walmart as a integration
4. Click Connect for Walmart
5. Follow the OAuth2 authorization flow
6. Grant the necessary permissions

The connection will be automatically established and ready for use with the E-commerce API.

Using the Walmart Sandbox

Note: Sandbox is only available for US marketplaces.

1. Log into the Channel Partner Portal with your solution provider credentials
2. Navigate to Sandbox Credentials
3. Copy the following values:
   • Client ID
   • Client Secret
   • Refresh Token
   • Walmart Partner ID

Configure the Walmart connector in Apideck

1. Log into Apideck Platform
2. Go to Configuration > E-commerce API > Walmart
3. Set the Client ID and Client Secret
4. Set the Server to "Sandbox"
5. Save your settings

Import the access token

Use the Vault API to import your Walmart credentials:

curl -X POST 'https://unify.apideck.com/vault/connections/ecommerce/walmart/import' \
  -H 'x-apideck-consumer-id: {CONSUMER_ID}' \
  -H 'x-apideck-app-id: {YOUR_APP_ID}' \
  -H 'Authorization: Bearer {YOUR_API_KEY}' \
  -H 'Content-Type: application/json' \
  -d '{
    "credentials": {
      "refresh_token": "{WALMART_REFRESH_TOKEN}",
      "access_token": "placeholder",
      "issued_at": "2025-01-01T00:00:00.000Z",
      "expires_in": -1
    },
    "settings": {
      "market": "us",
      "seller_id": "{WALMART_PARTNER_ID}"
    }
  }'

Validate the connection

Verify your connection is working:

curl -X POST 'https://unify.apideck.com/vault/connections/ecommerce/walmart/validate' \
  -H 'x-apideck-consumer-id: {CONSUMER_ID}' \
  -H 'x-apideck-app-id: {YOUR_APP_ID}' \
  -H 'Authorization: Bearer {YOUR_API_KEY}' \
  -H 'Content-Type: application/json'

A successful response returns status 200 with state: "callable".
